PuL's place is just as good as the pictures suggest, if not better. The bed is very comfortable and large, the aircon is wonderfully cold (even on the hottest days). It is nicely decorated, with lots of timber.
The bathroom seems to be new and spotlessly clean, and the shower is hot and strong. There were loads of fluffy white towels.
Technically, it is a studio, but it is a large one. I think 2-3 budget travellers could stay in this space comfortably. There is a sliding partition that allows the bed and office space to be separated from the kitchen/dining, which would be handy for those travelling with small children.
The building is quiet and residential. It is not a place to hold parties. This suited me, as I was in Bangkok to work. In any case, there are plenty of party places in Bangkok without doing it at home. That said, there were no issues with coming and goinfg at anytime of the day and people were friendly.
The building is a 5 minute walk from the BTS station at Aree. If you haven't been to Bangkok much, it is easy to underestimate the great value of being close to the BTS. It is the fast, cheap and efficient way to get everywhere in Bangkok, free of traffic snarls.
The street food in Aree is great. I recommend the pad thai stall that appears on the main street, not far from the station. Also recommended is the satay lady (my name for her) who is also on the main street, amongst numerous other vendors, opposite the pad thai place. There are also a lot of 'nicer' indoor restaurants, which is a good option for escaping the heat. Aree is a trendy neighbourhood and I suspect Japanese is the Thai hipster's cuisine of choice, as I counted eight Japanese places. I have eaten in many restaurants in Aree, inside and outside, cheap and not-so-cheap, and they were all great.
